SmileyProcter started 11 games at left guard for the Dallas Cowboys in 2008 but finished last season as their backup right guard. He was a coveted free agent after his release last week, making the rounds with several teams, including the New England Patriots.
Terms of the Smiley deal aren't yet known, and he must pass a physical before it's official.
Smiley represents another misfire by the Dolphins' front office. Football operations boss Bill Parcells and general manager Jeff Ireland made Smiley their first acquisition when unrestricted free agency opened in 2008, signing him to a five-year, $25 million contract practically at the stroke of midnight.
Smiley was a quality player when healthy but missed significant time with shoulder injuries and a busted up lower leg.
The Dolphins have made their share of mistakes in free agency, but they're not afraid to unload a player quickly when they don't think it's working out.
